International Auto Repair on Third Avenue in Chula Vista has operated as a transmission and general-mechanical shop since 1984, making it one of the longest-running drivetrain specialists in the South Bay. The ASE-certified facility rebuilds automatic and manual transmissions, replaces clutch assemblies, and performs four-wheel alignment alongside A/C system service, coordinating post-collision drivetrain work with CV Auto Body when accident damage involves both structural and mechanical components. Bilingual Spanish-English service covers Chula Vista, National City, and Imperial Beach, with complimentary local vehicle pickup available on major transmission and engine jobs. The shop's torque-converter rebuild bench handles lockup-clutch resurfacing and stator one-way-clutch replacement for GM 4L60E, Ford 4R70W, and Chrysler 42RLE units common in the South Bay fleet. Insurance-claim coordination through agencies such as Fiesta Auto Insurance & Tax Service streamlines the repair-authorization process for collision-related drivetrain damage covered under comprehensive policies. The highest-tier rebuilds include full hard-parts replacement with Raybestos or Alto friction modules, Sonnax valve-body upgrades, and dynamometer-verified output-shaft torque confirmation before reinstallation.
